All-Share Index gains 4% in March

Nigeria's equity market has entered a decisive phase of institutional maturity. The All-Share Index's 4.39% March 2026 gain—extending a six-quarter winning streak and pushing total market capitalisation to N129.2 trillion (approximately €170 billion)—reflects more than cyclical momentum. It signals that African's largest economy has successfully embedded structural reforms into its financial architecture, creating a more predictable investment environment for European institutions.

The catalyst is the Central Bank of Nigeria's post-recapitalisation supervisory framework, a critical but often overlooked development that deserves European investor attention. When the CBN mandated that commercial banks raise capital to N500 billion in December 2024, sceptics warned of market disruption. Instead, the banking sector completed the recapitalisation within months, with ten banks exceeding minimum requirements. But recapitalisation alone does not guarantee stability—the *framework* that governs deployed capital does.

The CBN's new supervisory regime introduces continuous stress-testing protocols modelled on Basel III principles, but adapted to Nigeria's specific macroeconomic volatility. Banks must now demonstrate resilience against multiple scenarios: naira depreciation shocks, oil price collapses, and sudden capital outflows. This is not regulatory theatre. For European investors, it means Nigerian bank balance sheets are no longer opaque boxes. They are subject to transparent, standardised scrutiny comparable to euro-zone banking oversight.

This matters because European institutional money—pension funds, asset managers, and family offices—had historically avoided Nigerian equities despite superior yields (10-15% total returns post-recapitalisation). The obstacle was not returns; it was *tail risk*. A bank could collapse without warning. A broker could evaporate overnight. Regulatory arbitrage meant rules changed based on political winds. The CBN's framework eliminates much of this uncertainty.

Consider the timing. As European Central Bank rates stabilise at 3% and German government bonds yield 2.3%, Lagos-listed bank stocks (Guaranty Trust, Access Bank, Zenith) now offer 8-12% dividend yields backed by Tier-1 capital ratios exceeding 18%. For a Norwegian pension fund or Swiss family office, that yield differential—5-9% above EUR baselines—is material. The recapitalisation framework makes that yield *claimable*, not theoretical.

The NGX's four consecutive monthly gains also reflect sectoral breadth. It is not concentrated in banks alone. Conglomerates, consumer goods firms, and industrial stocks have all advanced, suggesting institutional confidence extends across the economy. This diversification is crucial: it means European investors are not betting on a single sector or policy bet, but on Nigeria's structural recovery.

However, risks remain. The naira remains volatile against the euro (₦1,650/€1 current), creating currency drag for unhedged positions. Oil price dependency persists—a Brent collapse to $60/barrel would test the framework's resilience. And political uncertainty ahead of 2027 elections could trigger profit-taking.

Yet the directional case is clear: Nigeria is constructing institutional safeguards that rival emerging-market peers. The CBN's stress-testing regime is not aspirational; it is operational now.
